Carefully chosen low noise VHF/UHF/SHF yagi designs detailed here represent only the very best from Derek and his in-depth and ongoing research project, better at hearing weak signals. All are 50-Ohm direct feed, pure and simple. No need for folded dipoles, loops or bent elements making construction much easier!

G4CQM is the only Ham Radio yagi designer to fully embrace Q-factor and carry out a full and forensic analysis of each design which also includes TANT. This empowers end users with the necessary information and be able to select a design best suited to their own situation and climate.

Yagi designs sporting a low value Q-factor are more likely to deliver software predicted design parameters when constructed, an important consideration when making your final choice!

G4CQM is the Amateur Radio callsign held by Derek Hilleard, previously licenced G8CIW from early 1969.
